Contrastive Analysis of Deep-Water Sedimentary Architectures in Central West African Passive Margin Basins During Late-Stage Continental Drift

Journal of Marine Science and Engineering
The Lower Congo Basin (LCB) and the Niger Delta Basin (NDB), two end-member deep-water systems along the West African passive margin, exhibit contrasting sedimentary architectures despite shared geodynamic settings.

LiDAR mapping of the sedimentary rocks surrounding a salt diapir: a powerful tool to assist landslide identification and structural/depositional sequence analysis (Maestu diapir, N Spain)

Journal of Maps
A new 1:25.000 geological map is presented for a 26 × 22 km quadrangle containing the Maestu salt diapir and its sedimentary country rocks. A new mapping approach was followed to depict the distribution of interpreted late Cretaceous-Paleogene ...

Seepage system of oil-gas and its exploration in Yinggehai Basin located at northwest of South China Sea

Journal of Natural Gas Geoscience, 2017
Seepage systems of oil-gas in Yinggehai Basin are divided into two types, namely: “micro-seepage”, which is presented by gas chimneys and pockmarks; and “macro-seepage”, which is also called oil-gas outflow; and, in addition, the combination of the two ...

Diapiric Structures off Niger Delta

AAPG Bulletin, 1973
ABSTRACT Several marine geophysical profiles off the southern part of the Niger delta reveal the presence of diapiric structures beneath the continental slope and rise. The origin of the diapiric material appears to be deep in the sedimentary section and is believed to be of Aptian-Albian age.

Surface Deformation and Salt Budget of an Active Salt Fountain, Finu in the Zagros Mountains, Iran, Using Persistent Scatterer Interferometry [PDF]

Lithosphere
In subaerial salt diapirs, salt buoyancy drives the vertical flow of salt in the feeder, salt extrusion, and gravity spreading on the surface. The shape of these diapirs is controlled by the balance between buoyancy forces, gravity spreading on the ...

Dynamic accumulation of a high-grade gas hydrate system: insights from the trial production gas hydrate reservoir in the Shenhu area, northern South China Sea

Frontiers in Marine Science
The ultimate enrichment level and quantity of gas hydrate resources are influenced by the dynamic process of accumulation and preservation. High-resolution 3-D seismic data, logging while drilling (LWD), pressured coring, and in situ testing were used to

Three‐dimensional attenuation model of Sierra Negra Volcano, Galápagos Archipelago

Geophysical Research Letters, 2016
The shallow magma system beneath Sierra Negra was imaged using attenuation tomographic methods. The t∗ spectral decay method for P wave phases was used to highlight regions of high Qp−1 which suggest the presence of magma melt.
